The Indium Solder FLUXWV-84375-1G is a no-clean wave solder flux. WF-7742 is a VOC-free, no-clean flux specifically developed for Pb-free wave soldering of surface mount, mixed-technology, and through-hole electronic assemblies. WF-7742 is a water-based, nonflammable formulation that dramatically reduces VOC emissions and eliminates special storage requirements. A wide process window provides excellent solderability on difficult-to-solder assemblies and reduces solder balling.
